Something that has fascinate d me for a long time now is the mathemati cal complexit y yet mechanica l simplicit y of the Cycloid Reducer. Art, if you ever get bored and need a new project a hypocyclo id cam generatio n may be an interesti ng addition to Gearotic (perhaps ?). https://binged.it/2RxIHqKTweakie. |

Hi Tweaky: It was just released in Vexx, I just havent yet made a video on the topic.  Youll find a new button on the vex tools that calls up the cycloidic reducer tab. Art |

Thanks Art, that is a real co-incidence ( or is it sublimina l ) I will power-up Vexx and give it a whirl. Thanks again. Tweakie. |

Unfortuna tely... My version of Vexx is 2.24 which does not appear to have the cycloidic reducer tab and Win10 (in it's wisdom) will not allow me to download Current Developme nt 3.xxx (Click) Even disabling Defender Firewall and Smart Screen it still thinks the download contains a virus and deletes it.

Tweaky:
Did you try the win10 based .msi loader on the main download page? It usually works without complaint .

Thx

Kirk: Each f the component s, when generated, are grouped as to function. So, if you select just the rotor for example, you shoudl be able to select "extrude" in the tools and extrude just the rotor to an stl. I havent tested there at all, Im still finalizin g that module... Let me know how it works out. Art |

34 minutes, less if it fails, and I'll have at least the sun and planet (forgot the cycloidal reducer part names). The pins show up in PrusaSlic 3r but not in Repetier-Host so I'll need to look into that one. Is there only 3 parts?

With some random giggling I came up with this page which among other things included the attached picture that gives names (at least their names) for the parts. The pic shows a high speed shaft that looks a lot like a cage gear (although iirc the stl has bad pins), just leaving the low speed shaft and the way it connects to the ring gear. Do you have any plans to add something like these, or the parts in Tweakie's gif? The cycloidal disk and ring gear printed OK, although I really should take the time to properly get this new ender 3 pro printer properly set up, particula rly as my regular chair sitting time is slowly increasin g. Black 6mm pins are printing as I type this, will either post a photo or pretend it never happened depending on the results Kirk |

My camera thought it was a face The pins are oversize, 6.2 instead of 6.0mm so it's hard to turn, but turned out pretty decent. Kirk |

Kirk:
If you include the bearing ring, it becomes a different ial reducer, hold the ring and the center disk turns, hold the
centering disk and the ring turns..
I am designing a clock to use cycloidal s so Im hoping to hold the video until I can show at least one stage
operating . The shaft is usually the hard thing, but Im using small lazy susan bearings that allow you to simply
glue the bearing to the wood offset from center. Makes one easier to make out of wood.
